"Brick" means the external power supply - you know, that big black
square thing in the middle of your power cord unless you own an Apple
in which case it's white.

It takes AC in, puts DC out.  It will list on it exactly what it can
take in and put out.  What you care most about is output wattage.

The original factory one only puts out one voltage DC (or sometimes
two).  The "universal" ones have different tips, each tip "tells" the
brick what kind of voltage is needed at that tip shape.
